Fixed bug with scale command. Applied a temporary patch to the error printer which breaks when FINESSE reports the message '** Global scale factor applied to ALL outputs' - there's some sort of unicode thing going on

adding romhom greedypoint file parameter, changing SIfloat to convert numpy arrays, beam_param can accept numpy arrays for computing multiple points

fixing parsing of consts when used multiple times in a single line, also checks for math operations around const name in equation

adding in more ROMHOM computation and weighting file generations as well as some knm computations utilities. Adding more functions in beam parameter object for plotting parameters

adding lambda default wavelength property, also fixing q factor computations that need to link to this value

Adding in map reading/writing class and updates to various gui components, trying to get rotation working but failing so far
